I consider this a very good question!Actually most HD vendors list a MTBF (Mean time between failures) number for their hard drives. The thing to keep in mind is it is a "mean". Some drives last much longer, some drives die sooner.
Can some knowledgeable electro- mechanical "geek" out there answer this; and Is there any published data to back it up?
Any HD is a moving part. Eventually it will fail. The when is pretty much an unknown number. Most HD's will percolate along happily for years, however, I have had a HD fail within a month of installation. It was replaced under warranty, without a hassle, but that still did not do anything about the recovering the data from the old one.
The rule is back up, often. Then if it does die, restoring your data is not a crisis. At one time Seagate had SCSI drives for raid array use in servers that carried 10 year warranties. Those were also large, slow, and very expensive. It's pretty astounding to see drives that were over $2K each in 1996 being listed for $29.99 from surplus outfits. <G>
Buy a quality drive, from a reputable vendor, back your data up often and you have done all an individual owner can do. If a drive on an older machine, starts to give troubles with slow responses etc. .Don't hesitate get another drive and change it promptly. JM2�W.
